    try this. write only main bios 32Mb. It will enter in MPM mode, 1st time when enter in bios reset to factory defaults, save, restart, then enter again in bios and in Main tab you have "set machine unique data" and write this:

    HP ProBook 450 15.6 inch G9 Notebook PC or you can cut it to HP ProBook 450 G9

    after that save and use BCU 4.0 to exit MPM mode or restart laptop how many times counter shows.

        tried to flash main bios, resoldering and after attaching battery, keyboard lights 5x then when i press power, caps lock and numlock blink 7x simultaneously then powers off. pressing power again makes caps lock and numlock blink 7x.

        btw, it doesn't dislplay anything during the process.

          remove battery, also cmos battery, plug adapter and wait for 2 minutes, it will restart several times without displaying anything, don't press any button.

                If I understand right, I can also use this .zip but setup my Serial. Or it harder than I think? Is it possible whitout removing bios flash?
                Sorry for stupid questions, I`m new at this)

                  no, it's not possible if you have bios password. If you want to change serial, ID, name, etc. and you DON'T HAVE PASSWORD on bios you can use BCU 4.0 or higher.

                    No, I want remove password from bios, and save serial, windows key(if it on bios) etc. I just need to install windows (coz now it's working as "to go").

                      you can't use another bios from another laptop, your own bios has to be modified. "set UNIQUE machine data" does sound a bell?

                        Yes, shure. Is it possible by myself to modify bios? I can remove flash but I don't know how to use Hex editor to remove password...

                          I`ve compared bios from top of thread and the one you send, it have just 7 differences. Can I change my bios in same place or it doesent work like that? Also I`ve see solution to find and remove "nvramactiveRegn". Which way is better?
